Dolomite Launches the New Porous Media Chip Providing Rapid Advances in Petro-Chemical Research

Royston, UK (13th November 2012) – Dolomite, a world leader in microfluidic
design and manufacture, has introduced the new Porous Media Chip, which enables
statistically representative modelling of complex porous sandstone rock structures. The
chip will find application in academic research (earth science and engineering), the
petrochemical industry, environmental testing and groundwater analysis.

The chip features an idealised 2-dimensional net like structure of intersecting 100 µm
diameter capillaries, forming pore bodies joined by different types of throats. Pore
bodies and throats are assigned standard geometries to simplify structural modelling
and analysis. The chip can be used in single and multi-phase fluid (oil, water or gas)
flow studies through porous media. The results can be used to estimate and predict the
characteristics of soils and rocks.

Operating over a wide pressure range up to 30 bar, the Porous Media Chip is compatible
with Dolomite’s Top Interface 4-way and Linear Connector 4-way, allowing quick and
reliable fluidic connection to 1.6mm OD tubing. Capillary connections can be added to
increase the operating pressure up to 350 bar. The Porous Media Chip is also available
in quartz for improved optical transmission.
